Diluting spray tan solution involves adding a specific amount of water to the original formula, typically to lower the concentration of DHA (Dihydroxyacetone), the active tanning ingredient. This allows for a lighter tan result.
Simple Dilution Method
Based on common practice and the provided reference, a straightforward way to dilute solution for a lighter tan is by using a general ratio.
Reference Information:
As a rule of thumb, about 1/2 ounces of water should be added per 2 ounces of solution to lower the DHA by 2%**. Be cautious if you wish to make a larger amount of customized solution as a more precise calculation is needed.
This rule of thumb provides a basic guideline for reducing DHA concentration:
- Add approximately 0.5 ounces of water for every 2 ounces of spray tan solution.
- This dilution ratio generally results in a 2% reduction in the DHA level.
For example, if you have a 10% DHA solution and dilute it using this ratio, the resulting solution would be roughly 8% DHA.
Practical Dilution Steps
- Determine the desired amount: Decide how much diluted solution you need for a single application or a small batch.
- Measure the solution: Accurately measure the required amount of your standard spray tan solution (e.g., 2 ounces).
- Measure the water: Measure the appropriate amount of water based on the ratio (e.g., 0.5 ounces of water for 2 ounces of solution). Use purified or distilled water to avoid introducing contaminants.
- Combine and mix: Gently combine the water and the spray tan solution in a clean mixing container or directly in your spray tan gun cup (if diluting for immediate use).
- Mix thoroughly: Carefully mix the solution until the water is fully incorporated. Avoid vigorous shaking that can create excessive bubbles.
Dilution Table Example (Based on Rule of Thumb)
| Spray Tan Solution | Amount of Water | Approximate DHA Reduction |
|---|---|---|
| 2 ounces | 0.5 ounces | 2% |
| 4 ounces | 1 ounce | 2% |
| 6 ounces | 1.5 ounces | 2% |
Note: This table uses the rule of thumb ratio. The exact final DHA percentage depends on the starting DHA percentage of your solution.
Considerations for Larger Batches
As highlighted in the reference, the "rule of thumb" is best suited for small, single-use amounts. For diluting larger quantities of spray tan solution or aiming for a very specific DHA percentage, a more precise calculation is recommended. This involves understanding the original DHA percentage and calculating the exact volume of water needed to reach the desired lower percentage. Always mix a small test batch first when creating custom solutions.
Diluting spray tan solution allows you to customize the depth of the tan, offering flexibility for different skin tones and client preferences.
